What is modem short answer?
Modem is short for “Modulator-Demodulator.” It is a hardware component that allows a computer or another device, such as a router or switch, to connect to the Internet. It converts or “modulates” an analog signal from a telephone or cable wire to digital data (1s and 0s) that a computer can recognize.
What is the modem on a computer?
A modem modulates and demodulates electrical signals sent through phone lines, coaxial cables, or other types of wiring; in other words, it transforms digital information from your computer into analog signals that can transmit over wires, and it can translate incoming analog signals back into digital data that your …
Is modem and Wi-Fi are same?
